Quick Answers

What tools do you need?

Just the platform account.

How much does it cost?

No paid tools needed: this case uses only the platform itself, which is free to join.

Is it allowed?

Follow the platform rules and disclose ads.

Watch out: Self-reported, a team not a solo founder, and the numbers are from the first 48 hours. They list onboarding friction and agent speed as weak spots.

Try It Yourself
